To all whom t may concern.' y Be it known that l, .loi-iN l/Viiiniaii NA- sMiTi-I, a subject of the King of Great Britain, residing at Leegate 'Heaton-lilersey,

has particularl reference to machinesca-- strips of or-v pable of being used for gluing namental or decorative edgings or borderings to a main band before'its application to thebox. In my'llnited rStates Patent ,view and a sectional elevation ofan alternative ory simplified constructiom-Figure `5 .51' `being a viewlooking in the direction ofthe` f varrow 5 above Figure 6,'said` Figures 'and No. 1,208,819, granted to me Deccm-berl), 1916, it is explainedV (page'fi, lines G5 to that it is very desirable that the bordering `strips should be placed onL the linachine in their proper relative positions toeachother and to the main bandto which theyare to be attached. y l Y The mechanism illustrated in Figures 5 and 6 of the saidpatent, comprises two gluing rollers and two stripping rollers operating in two separate gap between them'through which` the glued ledgings are passed and unitedlto the main 1 bandA on the roller D2. This arrangement rested by has two draw-backs. The two pairs of rollers constitute a heavy load, the inertia -o'f which has to `be overcome byv the starting device every time the band is pulled foi"- ward, and whose momentum must be ar-l the catch whenthe pull ceases, and it is further very inconvenient tol pass the 'glued edgings through the' gap between the tanks vand unite them properly with the -mainloand. f

The object of the invention is, therefore,y

to provide improved means forv gluing not vonly the undersideof a hand,'but' also" to transfer glue from the gluing roller toa `portion of 'theupper surface of such-band or bands andA along one l or lboth margins,

\ and thus'male it possible to glue both the -mainban'd andthe strips, and unite `the three Ion a single gluingiroller, instead jof employing'a pair of'rollers and two tanks, a

I" thereby greatly*simplifying,both the ma.- chine and the work ofthe operator.'

'remove the rollslGr'and P' for cleaningyor `to "separate the bands from contact with the `roll Gr, in caselthe machine must remain ica where on the bar 3 are the guide plates 7,

which have forked ends to embrace the rod 8 lined in projections cast on the frame S, and which serve to keep the band between the guides 7 when the trame S is turned over. The edging strips 9 pass under a guide rollerlO, mounted in bearings 11, and a rod 12 lifts them when the frame S is tilted up.' Means, presently tobe described, guide the edging strips in their proper relative positions onto the glue roll (if, so that the mainl band A overlaps the margin of the strip or strips 9, a suitable amount as shown in Figure 3.v lt is obvious thatthe whole under surface of, the strip 9 will'be glued by contact with the roller C, but that the underside of the main band A will not be glued where it is superposed on the strip. This is because (see Figure 1) the strips 9 are led in between the roll Cr andthe band A. It is, therefore, necessary to put iilm of glue along the margins of the strips 9, on the upper surfacesthereoi', before the strips pass under the band A, which iilmwill be as wide as the overlap in order that the strips may adhere to the main band and that the bandv and the strip o -r strips will leavethe roll G as one'united band glued all over the under side. rlhis maybe accomplished in the followingmanner: Bearings 13 are 'formed in the frame S to receive a shaft B upon which are supplemental gluing rolls C movable longitudinally along and iixable anywhereI on the shaft B. Villen in working-position the rolls `Care pressed down on@ .the roll G by springs 14 resting l.on thel shaft ends. rlhe 4 width vof the-surface of yeach roll C is made about double they amount that the main band must overlap the strips, and they are so adjusted along the shaitr B that half their width presses on the upper surface of the .s margin of the strip, and therefore receives no glue while the. other half` isv exposed, and

jtakes up glue from theroll Gr.- The rolll C can be` adjusted along the shaft Bso as to occupy any desired position rela-,tively to the vlength of roll G. Y ln order that-the glue so taken up by roll C may be transferred to the upper margins of the strip, spreaders 16"' attached to the suitably inclined ends 16 of the arms 15 transfer the glue which has been taken upby each roll C on to that part of thesurface of said roll which; received no glue from the roll Then the-glue istaken f from roll C by the margin of the strip, as

indicated by the dotted lines iny Figure The spreader or transierrer 16u may be a thin copper blade. resting or trailingon thev strip if stout paper-is used.

` rllhe spreader' or transferrer is adjustable in the direction of its length, as by means of a screw 15a F igure), to vary the width of the glued margin of the strip.

Brackets 17 can be moved alongfand fixed anywhere on the bar 4 and carrypins 1Son which the spreader arms 15 are pivoted, so they can be turned backwhen it is necessary to remove the shaft B for cleaning. A stud 19, also tiXed in the bracket 17, carries a freely running double flanged roll 20. By any suitable means one of the flanges may be adjusted to suit the width of the strip to be used and a pin 21 fixed inthe bracket 17 serves tolreepthe strip between the iianges when the iframe S is turned over.

`ln this way by the use or" a single gluing roll one ortwo strips maybe properly united to the main band, the whole under sur-` Yface being suitably glued andall three `leave the single gluing roll as one united'y band, thus greatly"` simplifying the machine' and the work of the operator. i

vReferring now to Figures 5 and G, which illustrate a simplified construction by the omission of theV roll C and the iia-ngedroll 20, and by mounting the transferring spread er or blade close to the periphery oft'he glue roll G.

In Figure 6, aA frame F: is mounted to be swung to and from position, thev same as frame S in F igures 1 and 4. Said frame F carries or includes rods 30, 3 1, 32 and 33. Adjustable anywhere alongthe rodfO'are the guide lingers 36 to position the: main y band A, which 'is not shown in Figure 5, to avoid obstructionoi` parts below.l Ande for the same reason, the strip 9 and its gui-des 37 and 38 are not shownin quite their proper 36. lt will be'understood, however, that-they vcan be each moved. on theirrespective rods sok vposition in relation to theA mainv bandguigles stood that there may be two-sets. orfst-rip`v guides when it is required to employ atwo strips 9. vThe roll V35 revolves freely onl points fixed in theframe Rand the rod 3l 'prevents disarrangement of the band when the frame F is'lifted Similarly .the rodi 34 guides the stripk or strips 9 and theV rod32 prevents d-isarrangement thereof relatively to the: guides 37, 38, which can beY lixed anywhere along the` rod 33. .0n a-boss. of guide 38 (see. dotted lines in lFigure- 5) is pivotally mounted ya linger 39 kept in place V longitudinally yof the rod 33vby the guide l38 0n one side, and by a collarv heldfby a1 set screw 41 on the other. At the upper end of the finger 39 is a hooked copper blade 40 'fixed to, but adjustable on an inclined face on the under side of the finger 39. The copper blade rests on the roll G, and is kept down thereon by the Weight of the finger 39, which is quite free on the boss of the guide 38. The blade being inclined to the direction ofrotation of the roll G, causes the glue scraped from the roll to run into the pocket formed by the hooked end of the blade 40, and spreads a film of glue along the edge of the strip 9. The width of the film may be regulated by adjusting the blade on the finger 39, so as to project more or less over the edge of the strip. The under edge of the blade at the hooked end is relieved slightly so as to permit the paper to pass below it without raising it off the roll. A

The hooked or curved end of the blade Ll() is of such substantially semi-circular 'shape (Figure 5) that its end is located above the edge of the strip 9. Consequently any surplus glue collecting in the pocket formed by said hooked end will be returned on to the glue roll GQ and will not escape and form a rib of glue on the strip 9.

The blade is adjustable in the direction of its length, as is the blade 16il in Figure 2. The screw for securing the blade in its adj usted position is indicated by dotted lines in Figure rIhe adjustment of the blade, and the shape of its hooked end, enables a definite width of glue to be applied to the strip 9, Without depositing any surplus thereon.

In banding a boX the main band is usually superposed on the strip as the work looks neater than it would otherwise do; but by the present invention the margins of the main band can be glued and the decorative edgings superposed thereon by suitably arranging the guide rolls and spreaders.

I do not herein claim a banding machine having a supplemental roll or rolls C, such as is shown by Figures l, 2 and ,4, because thesame forms the subject-matter of my application, Serial No. 309,467, hereinbefore referred to.

I claim:

l. In a banding machines aglue-bearing roll, means for directing two strips of sheet material over the roll in overlapping `rela'- the two strips, the delivery end ofsaidscraper being curved to form a pocket.

2.V In a banding machine, a glue-bearing roll, means for directing twoy strips of sheet material over the roll in overlapping relationship, and means for supplying glue to the upper surface of the underlying strip, said means including a scraper adjustable according to the width of the overlapping portions of the strips, the delivery end of said scraper being curved to form a pocket.

3. In a banding machine, a glue-bearing roll, means for directing two strips of sheet material over kthe roll in overlapping relationship land means `for supplying glue to the upper surface of the underlying strip,

said means including a scraper having itsdelivery `end forming a pocket, the edge of which extends to a point to return' surplus glue over the edge of said underlying strip.

4. In a banding machine, a gluing roll,v

means for transferring glue from said roll to the upper side of a strip of paper or` similar material passing thereover, said means comprising a scraper adju'stably mounted to accurately determine the width of the strips of transferred glue, the delivery end of said scraper being substantially semiciroular to return surplus glue onto said roll. j

In testimony whereof I have aiiixed my signataire.
